IRA Money

Need your help! In light of what is happening in the stock market, we are afraid of losing our savings! We are seniors in our 70’s. Our IRA consists of $300K in a Vanguard Target Retirement Income Fund and 32K in a CD (5.25%). We do have $20K in a chicken money account. Should we transfer money out of our Vanguard fund into another CD or T-Bill within our IRA? Thank you!
