F you received a lump sum pension that you rollover into an IRA, and then begin withdrawing from it, is that still pension money when computing income taxes?

Company gave me option to take monthly pension vs a lump sum.  I elected a lump sum and rolled it into an IRA. I am not taking withdrawals from the IRA on a regular basis.  Is that money being withdrawn classified as a pension and treated that way with calculating income on state and federal tax returns?
