BOX 25 (Yes, it exists UNDER box 19B) on a NYC W2 - Please help on how to determine locality name after moving to PA

Spouse worked in NYC part year, then moved to PA, while still working in NYC.

 

The NYC W2 is populated as follows:

Box 15 Name of State: "NY"

Box 16 State Wages, ETC.: Specified dollar amount is entered.

Box 17 State Income Tax:  Specified dollar amount is entered.

Box 18A Local Wages, ETC.: Specified dollar amount is entered.

Box 19A Local Income Tax: Specified dollar amount is entered.

Box 20A Locality Name:  "NYC"

Box 20B Locality Name: BLANK - NO ENTRY

Box 18B Local Wages, ETC.: BLANK - NO ENTRY

Box 19B Local Income Tax: Blank - NO ENTRY

Box 27 Correction box - unchecked

Box 27 VOID box - Unchecked

BOX 25 AMT WITHHELD UNDER SEC 1127 - This box IS populated with a dollar amount.

 

I imagine that this amount in BOX 25 is possibly the tax that should be paid to PA, but one, I do not want to assume, and two, when the Turbo Tax software checks for errors, it is forcing me to enter a "LOCALITY NAME" in Box 20 for the amount entered in BOX 25.

 

Any insight, clarity and solution to this issue would be greatly appreciated.  Thank you!!!!
