Research Problem 5. Isabelle was contemplating making a contribution to her traditional IRA in 2020. She determined she would contribute $6,000 in December 2020 but forgot about making the contribution until she was preparing her 2020 tax return in February 2021. Use the website of any well-known IRA provider (e.g., Fidelity, Vanguard, T. Rowe Price) to determine if Sarah can make a deductible 2020 contribution to her IRA after the tax year has ended.
