You already filed 2019? Did you enter your S corp as a schedule C? Yes an S corp is a Business but not a disregarded personal business.
Home & Business Desktop program or the Online Self Employed version is for personal returns that include a schedule C for self employment or sole proprietor. A single owner LLC would be reported on Schedule C unless the LLC elected to be treated as an S corp or C corp.
You will get a schedule K-1 (or a W2) from the business return to manually enter into your personal 1040 return.
