Where do I enter my planned Roth IRA contribution?

[jeffki]

I am expecting an inheritance in the next few weeks. I would like to put $7000 (over 60) into my Roth IRA. Don't I need to enter this somewhere on my 2020 return?

No. You will record it when you do your 2021 tax return in early 2022.

But note that you can only make a Roth contribution if you have earned income. While the cash for it can come from the inheritance, the amount you can contribute is based on 2021 earned income from working.  Also see:

According to the IRS website I have until April 15th. I just need to know how to report it.

"Your tax return filing deadline (not including extensions). For example, you can make 2020 IRA contributions until April 15, 2021."

You can report the contribution on your 2020 tax return as long as you do it by the due date of the return, by using these menu tabs in TurboTax:

1. Deductions and credits
2. Retirements plans and Investments
3. Traditional and Roth IRA Contributions
