I do not know what a 1099r form is. I am assuming by context that you get one when you withdraw from your 401k which I did but never got a form

The plan administrator for the 401(k) is required to provide you a Form 1099-R by the end of January.

To enter, edit or delete a form 1099-R -

• Click on Federal Taxes (Personal using Home and Business)
• Click on Wages and Income (Personal Income using Home and Business)
• Click on I'll choose what I work on (if shown)
• Scroll down to Retirement Plans and Social Security
• On IRA, 401(k), Pension Plan Withdrawals (1099-R), click the start or update button

Or enter 1099-r in the Search box located in the upper right of the program screen. Click on Jump to 1099-R

Here's a blank one to see what it will look like
