I need help with a state tax return and I do not know what I'm doing. Please Help!

STATE TAX RETURN PROBLEM INSTRUCTOR: JUDY KNAPP F17 SE 2 ACCT318 PAYROLL & STATE TAXES Due date: December 20, 2017 Ronald (715-XX-0388) and Nancy (716-XX-0388) Studebaker are married filing jointly. They live at 5684 Beechwood, Your City, Your State, Your Zip which is within Your School District. Their phone number is 616-871-0594. Their birthdates are Feb 17, 1941 (Ron) and May 20, 1951 (Nancy). Ron is retired and has a pension that he draws on and receives social security benefits and has Medicare Part B health insurance premiums deducted from his benefits. Only $4874 of his social security benefits were taxable on his federal return. Early in 2016 Nancy was working full-time at K-Mart as a sales clerk and had federal, state and local withholding. Nancy's employer covers health care premiums for Nancy and her son. Ron paid Alfac Supplemental Health Insurance premiums of $438. Their federal AGI was $40,753. They have some interest earned from Fifth Third bank and have a little dividend income. They also have a US Savings Bond that is not taxable at the state level. Nancy has a 20 year-old son, Darren Ford (717-XX-0388; BIRTHDATE: Sep 18, 1995), from a previous marriage who lives with them and attends Davenport University. Nancy received $1200 last year in child support. Darren does not have the means to support himself and relies on Ron and Nancy. Ron's hearing has been deteriorating and he is now considered deaf. Ron and Nancy have never had the federal Earned Income Credit (EIC) disallowed. This year they received in federal EIC in the amount of $651. The Studebakers did not itemize deductions on last year's federal return. They would like to donate $20 to the Your State Animal Welfare fund on their 2016 return. The Studebakers were renting an apartment for $650/month for the months of January and February in 2016 from the Breton Road Apartments, 4200 Breton Rd, Your City, Your state, Your Zip Code. Their address was: 4267 Breton Rd Apt 38, Your City, Your state, Your Zip Code. They purchased a home and moved in March 1, 2016 to the Beechwood address. The property taxes for the year were $2,645, the mortgage interest for the year was $6,800 and the taxable value of their home is $82,000. Their DTE gas bill amounted to $2300 for the year. They have already filed federally but need your help with the state return. They will be returning on December 24, 2017 to sign their return. They would like to electronically deposit any refund received at their local Fifth Third Bank (Routing No. 072500042). Their savings account #: 123456. They forgot to mention but during your interview you find out that they bought laptops totaling $2,100 from Apple online and didn't pay any sales tax on them. Your state has a Use Tax. The Studebakers do not compute Use Tax on the basis of their AGI, only for large purchases upon which they did not pay any state sales tax. Please complete their tax return prior to their next meeting on Tuesday, December 24th
