No Taxes Paid

There were no taxes taken out because it was under the standard deduction for that job.  If that would have been your ONLY income, you would not have had any tax liability.  However, since you had more than one job, your total income was over your standard deduction and that $5,683 was added to your other income and became taxable. 

If you want taxes withheld more accurately when you have more than one job, on your W-4, you can have additional withholdings of any amount you choose.  If you have more than one job, this is a good way to not have to owe at tax time. 

You would enter the additional amount in Step 4 box c.  Be aware, if you choose an extra amount, that amount will be withheld on top of whatever you should have withheld for the week.  So if you choose $25 and you make $250 for the week, you would have $25 withheld that week.  If you make $500 for the week you would have $46 withheld (the $21 from the tax table and the extra $25 that you requested additional)
