Received early distribution from Retirement plan but don't have a 1099R
I recommend that you first contact the retirement plan administrator, as form 1099-R should be issued and given to you.
However, if you are unsuccessful, you may prepare substitute form 1099-R:
Click on Federal Taxes
Select Wages and Income
Scroll down to Retirement Plans and Social Security
Select IRA, 401(k), Pension Plans (1099-R)
On the screen Tell Us Which 1099-R you have, select I need to prepare a substitute 1099-R and continue; prepare the form to the best of your knowledge... be careful with the codes in box 7... it may be code 1 since you indicate that it is an early distribution...
