You're a year younger now than I was when I started getting more serious about my finances. So you're ahead of me in that regard.

I agree with others to open a Roth IRA. I'd do it with Vanguard, but Fidelity or Charles Schwab also are good options. Then put $6k in there for 2022, and when January 2023 rolls around put in $6500 for the year of 2023 (the maximum limit is going up by $500 for 2023).

Once money is in the account (the IRA is an account type), you still need to invest the money. If I aim for 40 years from now (when you're 66 and hopefully still healthy and alive), then I'd go for the target date fund of 2065 (okay okay, that's 42-43 years from now). For Vanguard that would be the Vanguard Target Retirement 2065 Fund, VLXVX for short. For Fidelity it would be the Fidelity Freedom® Index 2065 Fund Investor Class, FFIJK for short. The word index is important here because it means it's investing in indexes with low costs which is good and also the words investor class are important to get to the fund that let's you start with a "low" investment amount below 5 million). For Charles Schwab it would be the Schwab Target 2065 Index Fund (again: the word index is important).

Charles Schwab and Fidelity also have target date funds that are actively managed. They don't have the word "index" in their title and cost more but probably won't bring more profits. Hence my advice to go for the "index" variants. Vanguard's target date funds are always comprised of index funds.
