What would cause a huge drop in refund? 2021 income: $23k (W2), $7k (1099). Refund so far: FED ($9k), STATE ($1k). After added unemployment($34k) FED refund now $1.4k.

Just looking for speculations.  I have no idea besides either being in a higher tax bracket after adding unemployment or they took out more than %10 in unemployment income.   I'm in ILLINOIS. I know income tax on unemployment is fully taxed (first $10k no longer exempt). But I thought it's like only up to %7 or %10.  My FED refund was red$8k plus.   I filled out my income in order of W2's, 1099's and Unemployment so I didn't do anything out of the ordinary.  I already filled the EIC and Child Tax Credits prior.
