"Is that typical?"
It's not uncommon for a single account to contain multiple investments, although in the case of IRA CDs, some custodians prefer to treat each CD as a separate account. In this case, the code J indicates a distribution from your own account, not from an inherited account maintained as an inherited account. The amount distributed indicates that the custodian transferred your husband's Roth IRA to your own Roth IRA, probably automatically under the terms of the Roth IRA custodial agreement, and then made the distribution from your own IRA.
For the purpose of an IRA distribution, qualified first-time homebuyer is one who has not had an ownership interest in a primary residence within the 2-year period ending on the date of the acquisition of the new home. The distribution form the IRA would then need to be used for the first-home purchase within 120 days following the distribution.
If the contribution basis in your Roth IRAs (including the contribution basis you acquired from you husband through inheriting his Roth IRA) is greater than or equal to $29,645, the distribution from the Roth IRA is tax and penalty free no matter what you used the money for. Otherwise, the amount of the distribution in excess of your Roth IRA basis will be subject to tax and early-distribution penalty (unless some penalty exception applies).
