I agree with Critter. You need a conversation with customer support. Your post is very confusing and I think you are very confused. If you are working on a 2018 return there are not any Form 1040EZ or Form 1040A tax forms for 2018. For 2018 there is only Form 1040.
It sounds like perhaps you have an existing installment payment plan going for some past tax year, and have it confused with 2018's return somehow, You need a real time phone conversation to sort it out.
