I have downloaded the Mac Premier edition and it allows me to enter in multiple IT-203-F Schedule B forms but it still seems to require entering in Schedule A, as it seems to use the entry in line 1d for the New York State amount.
However, per the IT-203-F instructions (https://www.tax.ny.gov/pdf/current_forms/it/it203fi.pdf), restricted stock income requires filling and using the amounts in schedule B. The calculation must be made by Schedule B not Schedule A. Schedule A is mainly for income related to termination agreements per https://www.tax.ny.gov/pdf/memos/income/m10_9i.pdf
The IT-203 line 1 New York State amount should be the sum of all line 20 amounts from all IT-203-F Schedule B forms completed. The Schedule B information seems to be used nowhere and the application demands that something be put into Schedule A, which is not needed or wanted for restricted stock income.
At best I can sum up the totals in all Schedule B line 20 values and use that in Schedule A, or simply ignore these forms, fake a number for the allocation and manually edit the final NY return in forms mode to edit the NY source value, print out the forms, attach my hand-filled IT-203-F forms and mail in the NY return separately.
