Fd in personal or proprietor's name

For  FY 2018-19   50000  interest from FD + savings int is exempt under  sec 80TTB for senior citizen.

If i make online FD from current account it makes FD in the name of proprietor firm.

So GST turnover and  gross receipts are different. Moreover I am not sure whether i Will get exemption if FD is in name of firm ??.   Clarify this point.
