HSAs are individual accounts, not joint accounts. Your contribution cannot be made to your spouse's HSA and your spouse's HSA contribution cannot be made to your HSA.
In this case, the $775 contributed for your husband allocated to your husband all $692 of the family contribution limit for January eligibility plus his $83 catchup contribution. For the two months that you had self-only HDHP coverage plus your own catchup for January through March, your maximum contribution to your HSA (not your husbands HSA) is $691 for self-only coverage plus your $250 catchup for a total of $941. Your contribution of $1,550 exceeds $941 by the $609 that TurboTax reports. $1,633 is the amount that you could have contributed had the $692 for January family HDHP coverage not been allocated to your husband's HSA.
However, assuming that all of the contributions were deposited into your husband's HSA, your husband has an excess contribution of $1,550 to his HSA and you have made no HSA contribution.
