Easy solution. See the instructions in the TurboTax FAQ I'm linking below to enter this in your 2020 program. Please post back if you have any difficulty.
How do I get credit for a 2019 refund applied to 2020's taxes?
Your response only caused more questions. You need to try to follow your instructions because they didn't work as written.
I called in and they got me to where I needed to be for entry of last years tax refund.
The instructions I shared with you were written by TurboTax. Glad you got your issue straightened out.
Did the Jump To Instructions not work? People seem to have trouble getting to Jump To items to show up.
Did you find it here?
Federal on left
Deductions and Credits at top
Then scroll way down to Estimates and Other Taxes Paid
Other Income Taxes - Click the Start or Revisit
Next page scroll down to 2019 Refund Applied to 2020
Click Start or Update by the tax you applied
Then for state, you need to click on the state tab and go through state again for it to update.
Where did you get stuck? The instructions in the link worked for me.
