What does not able to efile due to one or more formset?

Try this to remove the formset error -

Delete the state tax return and then re-enter the state return

See this TurboTax support FAQ for deleing a state tax return - https://ttlc.intuit.com/community/using-turbotax/help/how-do-i-delete-my-state-return-in-turbotax-online/01/25895

This worked for me.  Just filed.

I'm having the same issue and I cannot use the former solution since I have already paid. I am trying to e-file rather than send by physical mail. I literally have nothing more than a W-2 on this. Please help.

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
Still receiving the message? We'd like to take a deeper look at your specific situation. Please attach screenshots, detailed instructions on where you are in the TurboTax Program and a token number. (This token number gives us your tax file with all your personal information removed)

This is just ridiculous!!! What if you have signed and registered? If I had to print and mail it to IRS, WHY DO I EVEN NEED TURBOTAX FOR? Very disappointed in the software and the customer service where I waited over an hour and still could not talk to a person.
