It depends. Check to see if Box 16 is blank or has a lower amount than the tax withheld in Box 14. If this isn't the case, i would suggest deleting the 1099R and then re-eenter again just to break this loop. To delete.
I have the same problem, I had originally entered it manually, then deleted and did an import from my bank and still get the same issue. This is an issue with Turbo tax. I have nothing listed in line 16. The previous years I did not have an issue.
How do I efile
I have opended a ticket with Turtotax support last night, there is nothiing we can do to resolve this issue, it's up to Turbotax to reo=solve
Many 1099-R forms are issued that have state withholding in box 14, but no box 16 state distribution. If you open up your TurboTax program and edit the 1099-R, on the screen that says "Enter your 1099-R details from [account custodian]", you can take the amount from Box 2a and enter it in Box 16 on this screen. That should clear any errors about withholdings being greater than distributions.
