GST AND TAX AUDIT

We are a GST registered Individual Taxpayer, in the year 21-22 we have a sales turnover 2.10 Crore, but unfortunately the builder stopped paying our bills for almost 60 lakhs, the builder did not pay TDS to us, now our CA advising us not to file audit and asking us to cancel those bills which amount is not paid, but we have already paid GST on 2.10 Crore. 

Can I expect an expert opinion on this. 

Regards
