Sounds like you need to have the FORCE with you.

Just a SWAG, based on what you said

It's actually not that serious. Version blocking is implemented when a program update addresses a calculation or e-file schema (code formatting) that prevents an incorrect filing and or e-file rejection from occurring.  

If you attempt to transmit a return when version blocking has been implemented, the system will not allow you to transmit the return until running the program update.

As usual, give your returns a second review for accuracy after running the update and before transmitting your return.

Thank you, Alicia.  I use the hosted product, so updates are done by Intuit.
