It's a stimulus payment, you should spend it in your local economy with local businesses if possible. This isn't free money to put in a savings account. The stimulus only works if you go out and spend it. The best way to spend it is to spend it with locally owned businesses. A single dollar can change hands many times in a local economy when spent with local businesses.
Treat yourself to some takeout from a locally owned restaurant, maybe get some car maintenance done at a locally owned repair shop. Donate a bit to the local food bank. Spend the money locally and stimulate the economy.
Some people will need to save this money if their job situation is shaky, or they have other bills to pay, but stashing it away if you don't need to completely negates the purpose of a stimulus payment. You should be spending this money, not saving it, if at all possible.
