When you say you downloaded the Business program do you mean Home & Business personal program or the separate Business program? The Business program only does Partnership, LLC, Corp. and Estate/Trust returns.
Yes you can enter 1099NEC self employment income into Deluxe and get Schedule C to pay the SE tax. Deluxe should work like the Home & Business version. Actually all the Desktop programs have the same forms. Did use the Desktop Deluxe or the Online web Deluxe?
You can try asking for a refund.
