I entered my businesses income and deduction info into self employed section but I elected to be a s corp through the irs, will it make a difference and do I need a k1

Sorry you can not enter it that way.  You do not fill out your business as self employed.  You need to file a separate S corp Business return.  Then only enter the K-1 into your personal return.

You need Turbo Tax Business.
TT Business is for 1120 Corporation, 1120S Corp, 1065 Partnership or 1041 Estate/Trust returns and will not do your personal 1040 return. It is a separate program from the Desktop Home & Business program or the Online Self Employed version.

You will get a schedule K-1 (or a W2) from the business return to manually enter into your personal 1040 return.

Turbo Tax Business is not available to do online or on a Mac. You can buy the Window's (Win 7 or newer) 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.
