This error normally appears when there are forms in your return that are not ready for e-filing.  You might try restarting the review and then filing steps and take note of any messages about forms not ready.  You could also continue the filing process and try just e-filing the Federal returns if it is your state you are working on now. You of course would then need to check back later to complete e-filing the returns or print and mail them if you wish.   -DMarkM1 Employee Tax Expert

Whats wrong that I cannot file my state

The state you are trying to file must be getting updated for changes from the American Rescue Plan Act.  I might recommend deleting the state return then re-adding and going through the state return again.  See if you get the same error when you are finished.  If you have already paid your fees, you will not be able to delete the state return.
