I am one step away from e-filing my 2021 1040 SR return. Turbo Tax states it is unable to transmit due to a Tax Program update that is required. How do I access that?

"TurboTax was unable to send your return to the IRS Validation failed: Tax Program Update Required. - There is an update
lie electronicalv. vou must get this update.
Looks like we had a technical hiccup?
