Yes. Did you take a distribution? You should get a 1099R for it. Do you need to know how to enter it?
The easiest way to get to the 1099-R entry screen is to simply search for 1099-R (upper- or lower-case, with or without the dash) in your TurboTax program and then click the "Jump to" link in the search results.
Enter a 1099R under
Federal Taxes on the left side
Wages & Income at the top
Then scroll way down to Retirement Plans and Social Security,
Then IRA, 401(k), Pension Plans (1099R) - click Start or Revisit
If you are filing a Joint return be sure to pick which person it is for.
Yes it is. Why are you asking? Did you take money out of a 401k account? Or put money into one?
