If you buy the Desktop CD/Download program you can use any version even Deluxe. All the Desktop programs have the same forms. You just get more help and guidance in the higher versions. You don't need the Home & Business version.
If you want to use the Online web version you need Premier to enter a K-1 (if she gets one from the business return) and to enter investment income. You should not need the Online Self Employed version.
