Some others have said, but it really matters how old you are and what your goals are. But as a general rule of thumb…
money for bills and monthly expenses can stay in a low-interest checking (or savings) account. Keep only as much as you need for a month, maybe a bit as a cushion just in case
money you’re planning on spending in the next 1-5 years in a high yield savings account (you’ll make higher interest) to use as “sinking funds” or an emergency fund (3-9 months worth of monthly expenses, give or take)
