I did a manual override to remove e-file diagnostics and e-filed approximately 7 returns before they changed the diagnostic. The manner in which I did this was, menu - E-file, E-file support tools - Disable e-file error. This no longer works, see below.
Now it reads, "Oklahoma Form 511-EIC is not final and will print as a blank sheet with an "Unavailable" notation until it has been released and/or approved by the State & Lacerte (ref #0)"
I know that typically it takes Lacerte up to 10 days to update a form once the state has approved it. The state approved the form, so I can only assume that it will be released by Lacerte possibly by the next update.
I would not override errors since this form is now blank. I am sure that Lacerte is working hard to get it updated.
