Deductions & credits

I had the same issue. Tried a couple of the suggestions of going back to the deductions and every time I went to review, it would decrease my expected Federal return and I guess change the charitable contribution. I went to fix it and read the instructions. For married filing jointly, the number should be 600 and not 300 as it was showing. I changed it from 300 to 600 and it worked. Fed return went back up and the review issue went away.
