Virginia Partnership Exempt from Nonresident Withholdings - how to enter?

[JustB22]

Filing a VA pass through return with nonresident owners, that qualifies for exemption from VA withholdings.  I cannot find a place in TTax "step by step" view to enter the exemption code.   When I switch to forms view and manually enter the exemption code on F502 Page 1 item (d), this correctly zeroes out the "Total Withholding Tax Due For Nonresident owners" on Page 1, Section 1, Line 1.  However, TTax does not seem to automatically update (zero out) the withholding figures on the Sch VK-1 Worksheets or the actual Sch VK-1s. 

Do I need to manually override every figure on the return that pertains to the nonresident withholdings, or is there somewhere in "step by step" view that I can make an entry that will appropriately zero out all the related figures automatically.   

Thank you in advance!

Hello I just had a call with tech support.  They did not know the answer.  When I asked them how the case could be escalated for review by the QA who tested this module, they said they didn't know how to do that.  When I asked if the case could be escalated for additional research, they said they didn't know how to do that.  I asked them what they recommended and they said I may have to do manual overrides for all fields.   Does anyone know how to get a higher level tech support review of these kinds of detailed state tax questions?
