Bond Premium on Treasury bonds

Hello,

1. I bought treasuries at a premium in 2023 with 5-10 year maturity

2. Will the amortized premium be deducted from the interest paid the bond in 2023 and every year following or,

3. Is the Premium realized as capital loss upon maturity or sale of the bond?

4. If it’s not deducted from the interest on my broker’s 1099 how do I elect to have it deducted in TT (if allowed by IRS)?

Thank You,
