Hi ,
Last year I was working on my OPt for 3 months but my FICa and MEDFICA taxes were withheld. So I had files for a separate form for erroneosly withheld FICa taxes. I received a letter from IRS saying that they cannot process my request since I had not files 1040NR when filing for taxes.
I had filed the following forms while filing for taxes :
Form 1040
Form 4868
Ca state part year return
Az state part year return.
Please let me know if I can do something about it ?

If you amend the return and attach Form 1040-NR to the amendment, it probably will not increase your taxes, but will then allow you to re-file Form 4868 to claim a refund for the withheld Social Security and Medicare Taxes.
