On the form 1099-R, between boxes 7 and 8, there is a small checkbox labeled "IRA/ SEP/ SIMPLE". It should be not checked.
Three things:
1. Checking this box will tell TurboTax that your retirement plan is an IRA, so you don't want it checked.
2. Did you import the 1099-R? If so, the import may have gotten confused. Write down the information on the 1099-R, delete the 1099-R, and then re-enter it manually and see if that fixes the problem.
3. If your 1099-R does have the box checked, contact the retirement plan administrator and tell them to correct it, because there are all sorts of consequences - especially at the state level - in confusing the two.
