Deductions & credits

I am having the exact same problem. Earlier in the year (mid February)  I do not believe I was having this problem as it  appeared that all the checks were successful and I stopped short of efiling  as I was waiting for one more 1099 to arrive. Now it appears that I can not efile. I get a screen that says I need to fix this problem during the 'complete check' review, which I do not recall seeing before.
