State tax filing

I am writing to say that this error persists in the 2023 Premier desktop version of turbotax. 

I have the same situation as the original poster (RSU income to be allocated to NYS across several years using IT-203-F).  I attempted to resolve this by speaking with a turbotax representative (who also read this posting) but there was not solution.

While I cannot get past the error message when using the interview, I notice that I can fill out forms manually and then select the REVIEW tab to finish the tax return.

Another workaround is to enter a large negative number in the "NOT allocated" box (such as -20,000 in my case) and mark it as estimated.  This allowed the completion of the interview process.  The final step was to remove this estimate.

Here is a screenshot of the error.
