Just a note on the withholding. I had 2 clients last year whose employers did not submit the W-3/W-2 reports to Social Security by 1/31/19 and both clients had to wait for verification of the withholding, by the IRS, until the employer finally submitted them to Social Security.

 One was out of business and that client's refund was delayed till December and finally released once a letter was submitted to the IRS by the employer verifying the wages and withholding. 

Your data entry may be correct, but that does not mean the IRS accepts it at face value.
