2018 Tax Return Amend

Hi,

I was married when I filed 2018 Tax, but my spouse was abroad and she didnt have her SSN, I filed as a Single. Now she is here and she has SSN. Is it ok to amend my 2018 tax and file as Married? We will have to use 2019 issued SSN to amend 2018 Tax return. Please suggest us. I am the Turbo Tax user since 2015.

 

Thank you
