It depends. In your example you made $24,000 in total which, if there is nothing else on the tax return, will be reduced by the standard deduction.
Using single, under 65, as the filing status the standard deduction is $12,550. The result is $11,450 as taxable income. If we go to the 2021 tax tables for this income amount the tax is $1,178 under the single column. You are basically at the 10% bracket so if we used even a few points lower on your $8k W-2 the tax would still be much higher than $247.
The Form W-4 is used so that your employer knows what tax to withhold, then it is also dependent on the number of pay periods and the gross pay per pay period. Employer withholding information can be reviewed in IRS Publication 15-T for 2022.
Double check your W-2s and the federal withholding for each of them. Then monitor your wages for 2022 with each pay check. You are allowed to submit a W-4 as many times as necessary to adjust your federal and/or state withholding. If your income will be similar in 2022, then you may want to add an additional amount on your W-4 (line 4(c) ) for job number 2. It's a good idea whenever you have two jobs.
