I need copies of W2's for 2015, 2016, and 2017. I need them to get a loan for a house. My email address is [remove].

TurboTax does not have a copy of the W-2 or Form 1099.  It would have W-2 and Form 1099 worksheets that included the tax data from the forms that were entered.  The worksheets would be included in the PDF of the tax return in the tax year the return was completed.  

Copies of a Form 1099 would have to obtained from the issuer of the form.

If you cannot obtain the W-2 from your employer, then for a fee you can get a complete copy of a W-2 from the Social Security Administration - https://faq.ssa.gov/en-us/Topic/article/KA-02501

You can get a free Wage and Income transcript from the IRS - https://www.irs.gov/individuals/get-transcript

For a fee of $50 you can get a complete federal tax return to include copies of W-2's, if you mailed the tax return and included a paper W-2, from the IRS by completing Form 4506 - http://www.irs.gov/pub/irs-pdf/f4506.pdf
