I have too much money in Money Market

Hi Terry. I have $346k in MM in my company’s (k) plan and additional $170k in 2025, 2035 target dated funds and Extended Market Index Inst Fund. Have a negative return on those three funds. I also have $120k in Chase savings. I’m almost 64, been retired for 1.5 years and am debt free. Suggestions where to move my savings balance? Was told to consider Merchants Bank of IN. I know i need to do something with my MM (k) balance. Living on $4k/month from pension and annual distributions from my (k) account. Thank you for your help.
