The TurboTax form 1040 [after Feb-5 update] says limit is $300 for MFJ when not itemizing. Actually it was raised to $600 for MFJ. The limit is $300 for an individual. So it should NOT report an error for amounts over $300.
The maximum is $300 on a 2020 tax return.
IRS Form 1040 (2020) Instructions page 29 - https://www.irs.gov/pub/irs-pdf/i1040gi.pdf#page=29
Line 10b
If you don't itemize deductions on Schedule A (Form 1040), you (or you and your spouse if filing jointly) may be able to take a charitable deduction for cash contributions made in 2020.
Enter the total amount of your contributions on line 10b. Don't enter more than:
• $300 if single, head of household, or qualifying widow(er);
• $300 if married filing jointly; or
• $150 if married filing separately.
