An easier, less painful approach is to click on "Forms", go the the offending 1099-R, click on box 9a and delete anything that is in that field, e.g. "0.0%" needs to be deleted. Run "Smart Check" again.
If you are in the middle of "Smart Check" and it is asking you to enter an amount, clicking on "Forms" will take you directly to the 1099-R box 9a. Just delete whatever is there and go back to TurboTax interview (just click on "Easy Step") and run "Smart Check" again.
