Tax due in 2024 is $2400 and in 23 was $493. $10K more income in 24 but $1900 more seems too high. Or should 23 be higher? 23 tax table says it should be $1378.

$10K more income but $1900 more tax owed. Somethings wrong

Nothing is the same as last year. There are many differences. If you have kids they are a year older. That can make big changes. Also the tax laws and brackets might have changed. The withholding tables change each year. Each year is separate. And another thing, more income = more tax and usually less refund or more tax due. It could be your withholding didn't keep up with the increase in income.

You have to compare this year with last year’s return LINE BY LINE and see what changed. Maybe you’ll spot something you left out or entered wrong. Common things are leaving the decimal point out or typing a comma for a decimal point, or typing an extra digit. Getting the wrong taxable amount on a 1099R entry or entering the 1099R wrong and getting hit with a penalty. Missing the qualified dividends in 1099-DIV box 2a. I could go on and on.

Do you have  any self employment income or a 1099NEC?  You might owe some other tax on it.
