Is her Single Member LLC an S Corp? If not it is a disregarded entity and goes on her personal return on Schedule C. Then does she have a separate self employment business?
If she needs to file a business return that should be done first to get the K-1 to enter into her personal return. Now she might need to amend her personal return. Did you and her file a Joint return? Or why are you filing Separate? Joint is usually the best way to file.
If she needs to file a separate Business return for the LLC, she need Turbo Tax Business. The small business program (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.
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.
