Deductions & credits

To reap tax benefits for making charitable donations, you must generally itemize your deductions rather than taking the standard deduction.

For 2021, if you’re claiming the standard deduction, this amount is up to $600 per tax return for those filing married filing jointly and $300 for other filing statuses.

You can correct your return(s) by logging back into your TurboTax program and following the steps below.

1. Click on the Federal Taxes tab.

4. Scroll down to Charitable Donations.
5. Select Update to the right of Donations to Charity in 2021.
