State tax filing

Thank you for the detailed explanation.
However, when I entered all her numbers on turbo tax (online free edition), she is not getting a full refund of the Ohio taxes withheld.
Her Ohio wages are around $8500 (box 16 of W-2) and Ohio state taxes withheld are $221 (box 17).
She also had other income of around $11,400 from her part time job in WV and excess scholarship (unearned income). Her total income was around $19900 (Ohio income $8500 plus other income $11400).
This is what Turbo tax said for Ohio:
Ohio taxes already paid $221 + OH credits we found $23 - total OH taxes $92 = $152 your OH refund

Shouldn't she be getting all of the $221? Why is Turbo tax  saying she gets only $152?

I don't know what went wrong. Should I delete both state taxes and start over again?
Any help would be appreciated. Thank you!
