In the interest of time, I'm going to leave you with the following info:
You only mentioned the SBA above when asked where you got info that there was no record. It doesn't sound like you have yet spoken to anyone at the IRS. If your efiled business return was accepted, then perhaps the IRS has not yet finished processing it.
Here's how to reach the IRS Business services help desk so you can ask them if they received your return and if it's still processing:
800-829-4933
7 a.m. to 7 p.m. local time
If you end up needing to speak to TurboTax Support, they can tell you if the efile was successful and accepted, and may be able to answer any other questions you have. Here's how to reach them:
Hours are 5AM-9PM Pacific (8AM-12 Midnight Eastern) 7 days/week.
