For tax year 2021, there does appear to be a UI to enter form IT-203-F, but it only allows entering a single form. Furthermore, it seems to also assume that one is filling out Schedule A rather than Schedule B (it pre-populates the income to allocate in line 1c, which is not relevant if one needs to fill out Schedule B).
If one has to fill out Schedule B, tax law requires filling out multiple forms if one has multiple grants per the description in Schedule B: "Complete a separate Schedule B for each option, stock, or right you were granted." This is even in the description in the UI.
There does not appear to be any mechanism to enter multiple IT-203-F forms. In the previous tax year 2020, TurboTax allowed uploading hand-edited PDFs. This is no longer possible either.
It appears that I cannot file my taxes with TurboTax as neither the old functionality of uploading completed PDFs is available, and the new functionality is broken.
