Deductions & credits

@MaryM428  - When I go to FEDERAL TAXES, Deductions & Credits, Charitable Donations, I can see the $300 of donations I made and entered into TT.  However, when I view my 1040, it says $0 in Lines 10a, b, and c.  How can I get my $300 to appear on my 1040?  We are taking the standard deduction.
