It sounds like you needed to give the FSA ID a day or two to process, and now it has completed processing. You can go in & make changes now (or at least should be able to make the changes).
But there may be an issue. Your maiden name was at the top? Did you change your name with Social Security when you got married? If not, you have a mismatch. Schools will most likely ask you for documentation to prove that you are the person with the name you used. And you need to change it for tax purposes. Several of us on CC, myself included, neglected to change our names with SSA when we got married. It caught up with me when I got a new job - I9 verification was a no-go until I changed my name at the SSA office.
