Deductions & credits

Thanks for answering. By the time I reached the $300 part of my Federal return TT must have fixed it because TT okayed my return. That particular screen needs to warn people not to type $300 into the box. I could see my actual cash donation amount shaded in the box but was told to leave it and Continue to next screen. I did and TT automatically filled $300 on my 1040 Standard Deductions return.
