I was able to fix the error by deleting all my 1098 mortgage interest data in the federal section. I then re-entered the information. When you do this the M1SA form is automatically removed and recreated which allows for it to be updated.
Also, before you re-enter the mortgage interest information make sure to check if any 1098 forms still exist. Do this to ensure there are no 1098 forms listed that may be pulling inaccurate information to your returns.
While in
your return, click on Tax Tools > Tools (in the black bar
at the side of your screen).
Under "Other helpful
links" click on Delete a form. If you scroll through your federal tax forms while in this section you will be able to see any 1098 mortgage forms that were previously created. If you find any, I would suggest you delete them before re-entering your information.
