Thanks to all that have replied.
In 2022 I converted an existing 401K plan from an employer that I was with for ~26 years (company A). The plan was managed by Fidelity, and I was able to roll it into a new "non-prototype" 401K account with Fidelity that allowed me to continue investing in stocks/bonds, etc. as well as check book access to invest outside the account. I was thinking/hoping I could withdrawal from this account prior to age 59 1/2. I'm presently 57 1/2 years old. However, I actually had a different employer for ~3 years after departing the first company mentioned (company B). From what I understand, the rule of 55 would allow me to access the funds (without penalty) from company B, but not company A. At this time, I'm still employed as a contractor with company C so I'm thinking the best thing to do is continue working until I reach age 59 1/2 and then I will be free to access my 401K funds penalty free and only having to pay taxes on withdrawals.
