It is not a bug, it is more of an issue of "order of operations."
Leave the box blank. But, you may need to revisit your entries.
The key is the sequencing of the entry in posting cash donations made and having TurboTax recalculate your tax breaks. Anything listed in the Cares Act section before first being entered as a deduction will produce unexpected results.
To do this in TurboTax CD/Download, go to Deductions & Credits and select I'll choose what I work on.
- First, enter in the charitable donation amount as you normally would in the Charitable Donations section of Deductions & Credits.
- When finished entering all donations, select Done with Charitable Donations and Continue.
- Scroll to the end of the Deductions & Credits page and select Done with Deductions.
- You may need to respond to any other additional questions, but eventually see: The Standard Deduction is Right for You!
- Click Continue.
- At Charitable Cash Contributions under Cares Act, you should see any qualified contribution amount already entered from your earlier posts. Select Continue.
For more information, see IRS Charitable Contributions Deductions.
