Where do i enter my taxes deducted already

They will be recorded when you enter the entire 1099-R in Federal > Wages and Income > Retirement.

Same screen that you enter the gross amount from box 1.

Enter a 1099R under
Federal Taxes on left
Wages & Income at the top

Then scroll way down to Retirement Plans and Social Security
Then IRA, 401(k), Pension Plans (1099R) – Click Start

If you are filing a Joint return be sure to pick which person it is for.

It's just as fast and easier to manually enter your W2 or 1099. Don't type the bank name or try to import it.
At the bottom pick - Change How I enter my Form

Then on the next screen pick - I'll Type it in Myself
