Hi, I filed my 2018 tax refund by mail and I get e mail that has been updated. Is there a something that I need to do more?

What is the difference between e file and file by mail

e-file means that your return is transmitted to the irs electronically. file by mail is when you send in your return through the post office. e-file is faster. If you have already sent in your return by mail, there is nothing further you to do.
