Two School district on W2

Hi there, 

 

In my W2, I just realized there is two school district on it A ($200) & B ($600).

I only live in district A, and since company is at B, they also charge district B. Both has the same amount of tax rate @ 1%.

 

1. Do i just add the two school district in the form ? Right now, I only have A, and I have tax due to school at #350. I feel that , if i add SD B, i dont have to pay tax or pay lesser?

 

2. I believe last year 2020, is the same thing, but i did not add the SD B in turbotax. can i claim it back?

Do, i file it as credit carryover for school district (B)?

 

Hope someone can help out!
