GST Composition scheme - registered but turnover less than Rs. 20 lakhs

Hi.

I am a service provider and in Oct 2019 had registered as a composition dealer before my turnover was Rs. 20 lakhs. Thereafter, I raised a few invoices (total turnover was still under Rs. 20 lakhs). After this, since I was able to recover GST from my clients, I opted out of composition scheme in Feb 2020 and moved to the regular scheme and raised invoices + GST (which was then duly paid/returns filed). 

My question is - am I liable to pay GST under the composition scheme for invoices raised between Oct 19 and Jan 20 even before the turnover reached Rs. 20 lakhs?  

Thanks in advance.
