You should have added this on your original thread. But if you didn’t have the tax withholding taken out in 1099R box 4 then how did you pay it? Oh, probably as an Estimated payment?
To enter Federal or State Estimated Taxes Paid, including a state estimated payment made in January for the prior year, go to
Federal on left or at top (Personal for Home & Business)
Deductions and Credits
Then scroll way down to Estimates and Other Taxes Paid
Estimated Taxes - click the start button
Federal Estimated payments should be on 1040 line 26.
