Hello, I filed an amended tax return which should have resulted in additional refund, but Turbotax shows nothing. How do I know the amount?

I thought Turbotax would display the adjusted return amount, but it's like adding another dependent made no change at all.

If you did an amended return it should have reset to zero for a refund.

If you then added a dependent you probably should have gotten an additional refund.

Be sure you posted the person correctly, and they fit this criteria.

You can claim your son as a dependent provided he meets the rules below.

Your son must be a U.S. citizen, a U.S. national, U.S. resident, or a resident of Canada or Mexico. There are certain exceptions for adopted children.
You can't claim someone who is claimed as a dependent on another tax return.
You can't claim someone who's married and files a joint tax return.
They are related to you? The child can be your son, daughter, stepchild, eligible foster child, brother, sister, half-brother, half-sister, stepbrother, stepsister, adopted child or an offspring of any of them.
Your child must be under age 19 or, if a full-time student, under age 24. There's no age limit if your child is permanently and totally disabled.
The child must live with you for more than half the year. Living at school as a full time student does qualify.
They may have a job, but they cannot provide more than half of their own support.
