what does the IRS WMR website say?
https://www.irs.gov/refunds
it's unclear as to whether you filed an amended return or the IRS just changed it.
for the amended return status -
https://www.irs.gov/filing/wheres-my-amended-return
to review a transcript of the return to see the changes were made if you did not amend
https://www.irs.gov/individuals/get-transcript
for other than direct deposit, if the website shows that your refund has been released but it's been more than a couple of weeks and you haven't received it you'll need to institute a refund trace. for direct deposit, if either the routing or account number are bad it could be months before you get the check in the mail. it's mailed to the address on the return so if you moved it will take longer.
