How do I enter the amount of my 2020 federal refund that I applied to 2021 federal taxes so that Turbo Tax counts that amount as part of taxes paid for 2021?

I have entered the amount of 2020 overpayment I applied to 2021 taxes in the Turbo Tax section "Income Taxes Paid / 2020 refund applied to 2021 federal taxes".  When I click "done" it takes me to a page that says "Amount of Extension Payment Made for 2020" and then says "We transferred the 2020 federal extension payment you made in 2021.  Make any necessary corrections to this amount".  I didn't file an extension in 2020.  Just filed / paid taxes on time.  If I ignore that page and hit "continue" Turbo Tax does not reflect the overpayment applied to 2021.  It reflects only my estimated taxes paid and is showing I owe federal tax when I know I don't since it isn't showing the 2020 overpayment applied to 2021.

Check your entries to make sure the amount of your 2020 Federal refund applied to 2021 taxes have been entered correctly.

1. Login to your account.
2. Select Federal from the left menu.
3. Go to Deductions and Credits.
4. Scroll down to Estimates and Other Taxes Paid.
5. Select Strat next to Other Income Taxes.
6. Scroll down and select Start next to 2020 Refund applied to 2021 Federal Taxes

MayaD says to scroll down and select Start next to 2020 Refund applied to 2021 Federal Taxes, but my version of Turbotax (Premier) doesn't have a menu item for that.

Turbotax says "we transferred the 2020 federal extension payment you made in 2021. Make any necessary corrections to this amount" but the box doesn't allow anything to be inserted into it.
