Should we have gotten a 1099g? My husband took 3 months off work under the CARES Act at the beginning of the pandemic, he received weekly pay. Box 14 on his w2 is blank.

Not necessarily.  He would only receive the 1099-G if his leave was paid through the government.   The question is more for your state return because some states handle PFL differently than the IRS.  

Paid Family Leave (PFL) income is money you receive from your employer, an insurer, or the government while you are away from work for an extended period of time so you can recover from a serious health issue, take care of a seriously ill family member, or bond with your newborn or newly adopted child.   

In the United States, employers who offer PFL are the exception rather than the rule. PFL is usually only available through larger employers, if it is offered at all. A small but growing number of states have enacted PFL legislation. They include California, Connecticut, the District of Columbia, Massachusetts, New Jersey, New York, Rhode Island, Oregon, and Washington. The National Partnership for Women Families keeps a list of state PFL laws. 

Paid Family Leave is different than paid time off like sick pay. For example, a new mother working at a company that does not offer PFL, might still take maternity leave based on accrued sick days. This pay falls under paid time off, and it is taxed differently than pay from PFL.

We've got instructions on entering your PFL income in TurboTax.   This is only for PFL on a 1099-G, so this does not apply to you since his leave was paid by his employer and was part of his W-2.
