Here's Intuit's suggestion for how the diagnostic could be cleared for efiling.

https://proconnect.intuit.com/support/en-us/help-article/adjusted-gross-income/resolve-lacerte-diagn...

ProConnect Tax equivalence of Lacerte input screen 53 is State & Local > Other Credits > Ohio Credit.

The line item is the same: Schedule 😧 Ohio AGI not earned or received in Ohio [Override]

This is the best alternative to overriding the ratio, an override that is not available, but you will lose IT NRC.

If you prefer not to override, the only option then is to paper file.
