State tax filing

Not an expert here, but I ran into the same problems with IT-203-F.   I ended up switching to desktop for the return since it properly saved the Schedule B and gave me the ability to look at all the raw forms and understand how they all connected.

Problem 1:  RSU Income getting double taxed / Not being able to set wages to 0.  

RSUs are considered part of your wages, despite needing to use a mulit-year capital gains income form to calculate them.  It automatically includes the sum of the IT-203-F Schedule B form in your allocations worksheet.  This is problematic if you only had RSU income to be allocated since you are not allowed to enter 0, and the federal value includes RSU income anyway.  

Solution: Enter NY Sum from IT-203-F as the value in your wages, and enter the negative value as the sum in the B field of the allocation worksheet.   This solution is hinted in the easy flow - "If the amount allocated to NY is included in wages or allocated on another line, enter the amount as a negative in the field below"

Problem 2:  Can not exclude Schedule A even though i haven't entered any data

Solution: There is a note on the top of schedule A that reads "For any wage that needs to be allocated on schedule A enter "M" in the Allocate by formula column on the new york state wages / self employment Income allocation worksheet".  

If you open up the form "NY ST Wgs/SE WK" you should see the income with an "M" next to it.  Clear the M and Schedule A will stop being populated while keeping all the schedule Bs entered.  This seemed to work for me without having any negative effects.  I dont think this can be done on the web version.  

This was all very frustrating to figure out.  Keeping my fingers crossed that i did it correctly.
