@nn18 , you have received an incorrect Form 1099-R. contact the payer to obtain a corrected form showing in box 1 the entire amount distributed ($6,500 + earnings), only the earnings in box 2a and box 2b Taxable amount not determined unmarked. If the payer refuses, you'll need to submit a substitute Form 1099-R (Form 4862) showing the correct numbers, marking and explanation.
Given how close we now are to April 15, it would make sense to request a filing extension for your 2023 tax return and pay any expected balance due.
