How safe in turbo tax free online ? I am uncomfortable sending PDF documents with my SS#.

[DoninGA]

E-filing a tax return does not use PDF.  The e-filed return is a data file that is stored on the TurboTax servers until the IRS or State pulls the return from the server to be opened only by the IRS or State.
See this IRS website for MeF (Modernized e-File) - <a rel="nofollow" target="_blank" href="https://www.irs.gov/e-file-providers/modernized-e-file-overview">https://www.irs.gov/e-file-provider...>
