Pa & DE State Tax Issue (Double Taxation)

Hello,

My wife works in DE and Lives in PA.  She got 2 W2s.  One for DE and one for PA.  They are identical except for entries 15,16 and 17 (State info and state wages).  I entered the DE W2 then added the PA info to it (DE and PA).

 

This is what I did:

 

In the PA interview "Updated" the "Income and Adjustments" section.  I arrived  at a page titled "Compensation Summary." There are two lines with the same employer with one having DE as state ID and the other PA.  I Edited the DE line.  Marked the "Entire Amount as non-taxable in PA".

 

I then went to the "Taxes & Credits/Taxes paid to other state" screen.   What should I enter in the following screens:

 

Under Gross Compensation: Delaware Amount (I assume this should be  Wages, tips, other comp)
    My wife's Amount  (what should be in there?)

 

Under Tax Due to Delaware on income above: Delaware Amount  (What should be in there)     My wife's Amount  (What should be in there)

 

 

Also do I need to file taxes with PA and DE or only PA?

 

Thanks,
