Deductions & credits

More specifically, I entered $5576 in charitable deductions, and the program forced me to enter only $300 for charitable deductions on line 10b of 1040 form.  I wasn't directed at all to complete a Schedule A even though the program said I'd save $12 by doing itemized vs standard deductions.  $12 isn't much. So rather than delay I simply went with the only choice the program was giving me - Standard Deduction. That part was confusing and there was no explanation during the process, at all.
