I lost my W2 from OSH, put do have my last check stubs

You should contact OSH immediately to request that they re-issue this W-2.

You shouldn't file your return without the W-2 you've lost. 

First off, you need to wait for a new W-2 to arrive so that you can e-file.  To file a return without your W-2, you have to complete Form 4852, Substitute Form for W-2, and you can't e-file this with your tax return.

Secondly, the information on pay stubs often doesn't correspond with what's on your W-2, so you could be entering incorrect information.  This could not only affect the tax you pay, but any credits to which you might be entitled, as well.
