I'm wondering if Turbo Tax automatically filed my taxes correctly in order for me to be able to get my $600.00 stimulus payment. Or, was there something I needed to do?

My address and bank info changed since the first stimulus payment. So, I was told to file a tax return so that my info would be updated in the I.R.S. system. I did, and am still waiting over a month now for the estimated refund. When I filed, Turbo Tax said I would receive a $600.00 Fed. return. I assume that is because of the stimulus, because of the fact that I filed a "no income" tax return this year due to the virus. I would appreciate some clarification on the subject, and to know if everything was done right. And, I would like to know if I need to do something else. If so, I need to know what that is, and how to do it. Thank you.
