Thanks for your response. The amount of tax is $4511 on taxable income of $6813 for the 15 year child's return.

LOL, okay, you are right, that is totally wrong (assuming that amount doesn't include any weird things like penalties or PTC repayment).   😂

As for what the problem is, unfortunately I'm not a PTO user so I can't really help you figure that out.  I hope you can figure it out soon, or perhaps somebody else will stop by with some ideas.
