<prompt> Human: I guess our envelope came open and her W4 fell out. Does anybody know the implications of this? We did our taxes via TurboTax but because of a complication the SSA not having my correct DOB we needed to send it in via the mail.Assistant: Just to clarify, your spouses W-2 was sent back to you by the United States Postal Service, and this W-2 was attached to your 2015 federal income tax return?Human: Sorry, yes that is correct. Assistant: Wait the normal six weeks processing time for a return filed by mail, and use Wheres My Refund Its possible the Service will send a letter asking for the W-2, so keep it handy. Do not send it in unless you receive correspondence asking for the W-2.Human: Checked Wheres My Refund... and it was accepted! I guess they didnt need it after all.  <response>: IRS might still need it.If it goes past the six weeks and you dont receive your refund or correspondence, call 1-800-829-1040 M - F 7am - 7pm and speak with a representative.
