State Farm - how long did it take you to receive payout after you submitted your personal property inventory through claims experience?

I submitted my claims 3 weeks ago but they still haven’t begun processing inventory. How long should I expect this to take?

Had a house fire late last year. Submitted inventory early Feb. approx 900 items. Coverage has been determined and everything in the house is a total loss. They paid half of my contents up front and told me to itemize for other half. I’ve been told it take a week, it would be done at the end of the week, that 15 business days is standard, that there is non time frame… etc. everytime I called I get different information.
