Do you mean you used the online program and entered 2017 income? If you did that it was a big mistake. The online program is only for 2019 returns---no other year--and you cannot change the year.
Did you e-file or try to e-file it? Was it accepted or rejected? Hopefully it was rejected--or you have a bigger problem to fix.
Tell us your e-file status so we know how to help:
