To treat your spouse as a US resident for tax purposes and file jointly, your spouse need an International Tax ID number (ITIN). You get this by filling out form W-7, the ITIN application, and attach the W-7 and any required proofs to your tax return, and mail it all to the address for W-7 processing. After the IRS issues the ITIN, they will process the tax return.
To get Turbotax to allow you to print your return, you may have to use a fake ITIN, try 999-88-9999. Cover it up with white-out before you mail the return. (You can't e-file this situation.)
I'm also not entirely sure how to get the papers signed by your spouse. I expect you will need to send the completed forms to your spouse by express service for a signature, then have your spouse express them back to you or directly to the IRS.
