I had typo in the last name of the person I filed for. The IRS has accepted the 2018 return. All other data on the return is accurate. Should I file an amended return?

After you file

If the IRS accepted the return, you don't need to amend.  The IRS didn't see an issue, so will process the return normally.

After you file

Only the first 4 letters of the last name need be correct ... there is nothing to fox for this year's return ... next year make sure to correct the mistake.
