Do I have to file an amendment

After I filed, I found another Form 1098 Mortgage Interest and more charitable contributions.  When I went back into the software and entered the information, it did not change my Federal but it changed my State return.  It seems to say that I would get an additions $242.  Since my Federal did not change, so I have to send in an amended tax return to show the additional 1098 form.  I forgot our mortgage was sold in March of 2019.
