You have created a mess by changing the federal return to file the state before using the amendment process. So because you only need to amend the federal return you can do it one of 2 ways ... use the one that makes more sense to you.
1) paper file the 1040X ... using the figures off the original 1040 & the updated 1040 complete the amendment form by hand and mail in the 1040X with the w-2 form attached. https://www.irs.gov/pub/irs-pdf/f1040x.pdf
2) undo the changes you made then start the amendment process to make the changes to both the fed & state returns then just efile the federal. Amendments cannot be done until late february.
