I was told I'm not elegible for stimulus checks so I did return to the IRS. Turbotax informs me now I am eligible for both stimulus. Should I put I received $0?

I was told by the Sprintax team, I was not elegible for the COVID 19 stimulus checks because we were not consider residents at the time we received the first stimulus check so we did return the stimulus to the IRS. Now in the 2020 Tax filling, the system informs me we are elegible for both stimulus checks (1st and 2nd one). Should I select I didn't receive the 1st one?

The answer to your question lies in your answers to the qualification questions below.  These are likely the qualifications that Sprintax used. 

In your 2020 Federal 1040 tax return, you will enter $0 in the stimulus payment amount amount if you qualify for one or the other stimulus payment.
