Welcome to the forums Sunny. As the others have said, if you don't know where to put your stash of cash at least put it in a MM for now. A 1% interest rate is costing you over 2% per year in lost value through inflation so you are really losing twice what you are making right now.
Shop around for MM funds. Vanguard is around 6.3% but others may be higher or lower. A lot depends on what you want to do with the money and when you need it. A MM is fine for a while but long term growth will require some equities (start with index funds if you want someone else to do the heavy lifting) to keep ahead of inflation and to make your money really grow.
