I'm sending a 2nd amendment which changes an amount owed for 1st amendment to a credit for the 2nd. Should I still send in the amount owed from the previous amendment?

1st amendment was a forgotten w-2, so I owed more than original. 2nd was for 1098-T, and 1098-E so I ended up with a credit. Should I send that amount due for 1st amendment and hopefully get it all back + some once they get the 2nd one?
