Can I just use a K-1 form and 1120 forms from IRS website, fill it with zero entries and send it to IRS?
You can do that but make sure you download a Form 1120-S for an S-Corporation. An 1120 is for a regular corporation.
is Premier good or should I get Home/Business TTAX?
Because of the consulting business you would need Home and Business. Premier will not create business schedules.
