It is possible that you could receive a second 1099G from the California Employment Development Department (EDD), but not at all guaranteed. As you probably know, your husband's unemployment compensation is taxable by the federal government (the IRS), but is otherwise California state tax exempt.
You would only get a second 1099G for the state disability payments if they were determined by the state to be a "substitute" for unemployment compensation. In that instance the tax treatment of these benefits would be just the same as described above. However, if you do not get a second 1099G, then you can safely assume that the CA EDD disability payments are completely non-taxable.
Here is what the state of California has to say on the matter (exact quote):
"State Disability Insurance (SDI)
SDI provides temporary payments to workers who are unable to perform
their usual work because of a pregnancy or a nonoccupational illness
or injury. Beginning July 1, 2014, California workers may be eligible to receive Paid Family Leave benefits when taking time off of work to
care for a seriously ill parent-in-law, grandparent, grandchild, or
sibling. SDI benefits
are taxable only if paid as a substitute for unemployment
insurance
(UI) benefits. This could occur if a person was receiving UI
benefits
and then became disabled. When SDI benefits are received as a
substitute
for UI benefits, the SDI is taxable by the federal government
but is
not taxable by the State of California.
You will only get a Form 1099-G if all or part of your SDI benefits
are taxable. If your SDI benefits are taxable and you don't receive
your Form 1099-G by mid-February, you may call EDD at (800) 795-0193
to get another copy."

Hopefully that provides enough information for you to determine a path forward. That is, you can either file your tax return(s) now, or you can call the CA EDD as ask them if another 1099G will be forthcoming.
Thanks for asking this important question.
