Hi Spata1357, thank u for ur response. But, we already filed 2019 tax return and it is already in process before I fill out the non filer form. This year tax filed as married filing jointly. Also, if IRS were suppose to void then I should have got the rejection email saying that my ssn was already used but instead I received "IRS accepted my return". So, this was the confusion as I thought I messed up our return.
