The problem in TurboTax Online has not been fixed. If you do not have any Form 1099-R for 2021, there is no way to include Form 5329 in TurboTax Online. The only way to do it is in forms mode in the CD/Download TurboTax software.
You can switch your tax return to the CD/Download software without losing anything that you have already entered. You will still be able to e-file.
How do I switch from TurboTax Online to TurboTax CD/Download?
Once you have your tax return open in the CD/Download software, switch to forms mode. Then click the Open Form icon at the top left, and open Form 5329. (There are two copies of Form 5329. Form 5329-T is for the taxpayer, and 5329-S is for the spouse on a joint return.) You only have to fill out Part IX, which is the last section all the way at the end of the form. On line 52 enter the RMD amount that you should have taken in 2021 (or by April 1, 2022). Enter zero on line 53. Between lines 53 and 54 there is a box where you can enter the amount you are requesting a waiver for, which would be the same amount that you entered on line 52. TurboTax will make the necessary entries on lines 54 and 55. Then click the Explain button to open the Explanation Statement form and enter your explanation. In your explanation statement, briefly state the reason you did not take the RMD, to show that it was "due to reasonable error," and state that you have rectified the error by taking the distribution in early 2022.
The Form 5329 and the explanation statement will be included in your tax return. TurboTax will include Schedule 2 in your tax return, with zero on line 8.
