How can I file an extension if I don't have my w2s to see how much has been paid? I have misplaced them during a move and am trying to get copies. I will not owe any.

If you don't see the extention form when you first open up the federal file follow that link to get a extention form.

I know where to go in Turbo Tax, but it's asking me how much have we paid over 2018, and to add up our w2 numbers, which we don't have, what do I do then?

WAG... guestimate it.  If you have a paystub with ytd info extrapolate from that. It is trying to help you figure if you still will owe. if you know you are not sending in an additional payment because you have a refund it will not matter.
 This year some people owe when they are used to getting a refund since that tax laws and withholding amounts changed. The extension is only to give you time to not to pay your taxes.
