if you used the above software what you did was submit your 2018 return using 2017 data.
there
is nothing you can do now. wait to see if its accepted or rejected. if
rejected (it probably will be if you had a W-2 because there will be a mismatch) you can fix and resubmit. if accepted, you'll have to wait
until you receive your refund or the IRS accepts payment for the balance due
and then file an amended return.
don't forget to file your 2017 return which needs 2017 software and you can no longer e-file it.
