State taxes for state I didn't live or work in on W2

I live and worked in Florida all year.

My employer is based out of Iowa but work is here in Florida where they opened a location

They took out taxes for Iowa, but stopped when I brought to their attention.

My W2 has line 15 IA and line 16 showers an amount for wages but not my full amount of income and line 17 state tax has an amount $221.53

I am filing my annual federal taxes and am doing the states for Iowa so I can get a refund, but it shows a refund of $70 instead of the full amount I paid out, it showed nonresident and I never worked or went to Iowa. On the states income should I zero out the amount shown on line 16 where the states ask about wages and Iowa sources to get the full amount paid out or do I have to leave  the amount from line 16?

I would be out a refund of $152 if so. Which I don't see why I should be out of I didn't live or work there at any point?
