How can I make it switch it itemized deductions? It's refusing to update even when I select itemized (on its own recommendation).

The system recommended itemized deductions but when it reviewed my return, it forced me to enter $300 under charitable deductions on one spot on my return. That seems to have gotten it "stuck" on the standard deduction, which is less beneficial for me. I've tried to change it to itemized, but it won't reflect the change even after I click it. How can I fix it?
