It sounds like your tax return contains IRS forms or schedules not on the accepted Forms and Schedules list.  If this is the case, the return is not eligible for e-file. 

The fee you paid for TurboTax Deluxe is for the preparation of your taxes.  You can still print and mail your completed tax return.  Refer to the following Help Article for instructions:  TurboTax Help TurboTax Help Intuit How do I print and mail my return in TurboTax Online?

I also got this message. However I checked the list and every form and that is on my tax forms when I pull it up before completing the efile portion is on this list. So can you please let me know if there is some other reason for this message?

We have received numerous reports of this experience that appear to be coming from various areas of the program. Please troubleshoot with the options below. If needed, we will need to investigate your experience.  Thank you for your participation and patience. 

A. Check Availability

Please confirm all forms you are filing are available and supported to be e-filed. When will my forms be ready?

(The 8915-E Form is projected to be e-fileable starting 02/24/2021)

B. Remove state and try again
 If all your forms are ready and available to be e-filed and you receive this message, please follow the steps below:

1. Sign out of TurboTax.
2. Sign back in.
3. E-file the return again.

You may need to remove your state and prepare your state return again to move past the error and successfully e-file.

C. Send us your tax file
