Can you show me how to fill those taxes on case 1, that was from 2017 tax return while they are in 2018 tax return. Do I need to fill federal taxes, state taxes on the same form with 2018 or just ignore it?

1.The Gonzaleses filed their 2017 federal, state, and local returns on April 12, 2018. They paid the following additional 2017 taxes with their returns: federal income taxes of $630, state income taxes of $250, and city income taxes of $75.

Do I need to multiply 1,500 by 4 quarter, 300 by four quarter and so on? In the last case, the problem provide me those taxes withheld already. I don't know how to handle it the second time here. I should combine the last taxes with this one?

2.The Gonzaleses made timely estimated federal income tax payments of $1,500 each quarter during 2018. They also made estimated state income tax payments of $300 each quarter and estimated city income tax payments of $160 each quarter. The Gonzaleses made all fourth-quarter payments on December 31, 2018. They would like to receive a refund for any overpayments.
