Series I Savings Bond

I bought a bond for the first time in July 2022. I assume there is no 1099 till it is cashed. You mention (somewhere)l that what gov took from my bank account would be less than bond for interest up front. The whole $8K was deducted. I also went on the treasurydirect.gov to see what interest was accruing but it just shows 8K. Again, not sure how this all works. Can you fill me in please? Thanks.
