Taxes rejected; update not due after State deadline

I'm a bit stuck here. My Federal taxes were rejected due to something wrong with the Self Employed Health Insurance deduction.  As a result, my State are also rejected.  My State are due 4/20/21, as my State has not extended the deadline.  TT tells me that an update to the SE Health Worksheet will be released on 4/30 - after my State deadline.

 

I tried calling TT for input, but the representative was beyond unhelpful - she wouldn't even believe me that my State hadn't extended the deadline. She then told me it was my fault for not filing back in February. Absolutely shocking. I'm basically stuck - I cannot use TT to file my taxes at all.
