Your employer corrected your W-2 for a middle initial?  Was the Social Security number correct on the original W-2?  The address on the W-2 is irrelevant.  People move all the time.  What matters is whether the employer used your correct Social Security number and entered the correct amounts for your wages.  You do not need to amend for a middle initial or for an address an employer put on a W-2.  Relax and enjoy the fact that your tax return was processed and you received your refund.

Thanks for replying @xmasbaby0. Both the W2's have the same SSN which is there in W2c. One thing I noticed and didn't understand in W2c, is that the SSN number is placed in a box called correct SSN (its the same which is there in both W2's).

But if I assume that that SSN will not be a problem and also the address and middle initial l as you said, does it mean I need not file for amendment?

No you do not need to amend your tax return for this.  You should, however, ALWAYS save your W-2's for your own records, so put those away with the originals you received from the employer in January and save them for yourself.

Alrighty @xmasbaby0 , thanks for your insights on this. I won't be worrying about the W2c amendmnet. And yes I do have the w2 saved in a safe place. Have a good one
