In PA , my Medicare wages are greater than PA wages in box 16, because I contributed to a TSP military retirement account. Do I have to do a PA-40 W2 RW?

This is not an IRA , and I didn't take any money out , just contributed. I'm active duty

No, not as long as your TSP contribution is reported on your W-2.  It should be in Box 12, with code D.  According to the Instructions for PA-40 W-2 RW:

The W-2 RW must be completed by taxpayers when the amount shown as Medicare wages in Box 5 of the W-2 are greater than Pennsylvania wages shown in Box 16 and there is insufficient information included on the W-2 to reconcile the wages without the additional information represented on the W-2 RW.

Your W-2 contains sufficient information to reconcile your wages without any additional information.
