I don't know which return to use for a Trust Foundation. The Business one asks me personal questions that do not apply and a space for SS # no Tax ID#

What kind of return do you need to do?  A 1041 Trust/Estate return?  Or a 1120 or 1065 Business return?  For all those you need Turbo Tax Business.  

Turbo Tax Business  is not available to do online or on a Mac.  You can buy the Window's version here.  And you can have both TT Business and TT Home & Business (or any personal version) installed on  your computer at the same time.

Or will this help?

Most federally tax exempt non-profit organizations file Form 990 returns. Turbo Tax does not support the Forms 990 series in any product.
