Thank you @xmasbaby0 for replying my queries.
It is understood that paper returns is taking longer time then routine due to Pandemic situation. However, the checks (for additional tax payment) which I enclosed with USPS mail were deposited and got cleared through my bank account. That means someone from IRS had open my enveloped and might had looked at my tax returns.
This surprised me because tax payment is done through check but the tax forms were not processed in the system. Any thoughts or experience for this issue.
