I'm using the online version and I was getting the same IRS rejection as others because of Turbotax putting "coronavirus" on Line C of form 8915-F. What I was able to do to fix it...
1. Start that section again and UNCHECK the coronavirus box. Then on the next screen I picked a random disaster and then went through the rest of the questions.
2. Go back to the beginning and go through the questions again. Leave the coronavirus box unchecked... but instead of picking a random disaster, choose the very top option in the dropdown list which is blank. This will delete the code TurboTax is putting on Line C.
3. Go back to the beginning and go through the questions again but this time check the coronavirus box.
I was able to submit to the IRS after doing this. I just got an email that it was accepted.
