Anything else after submission I need to do?

Paid fees on gov.UK on 11th Feb and Submitted my application on 22nd Feb. Anything else I need to do? No edits have been received so far on my application.

Did you get a confirmation from Tech Nation?

I got email from technation that my application has been submitted and email from that my application has been referred to technation

That’s all there is to it till you get an email from the home office about the outcome of your endorsement application.
