You are correct, those Forms 5498 indicate that corresponding accounts received no contributions or Roth conversions, indicating that those forms are not from the accounts that received Roth conversions. Regarding the Forms 5498, you said "I" have forms, which is ambiguous. If Form 5498 #1 is from an account belong to your husband, this indicates that your husband had a year-end balance in traditional IRAs of $5,248.80 (which rounds to $5,849), likely resulting in the Roth conversions being somewhat taxable.
