After I completed filing my 2018 tax return my husband received a 1099 for a job we placed on our return as cash. Do I need to amend this prior to starting my 2019?

No. It does not affect your 2019 return.

Depending on how your reported the income, you may not need to amend 2018.  A 1099-Misc, with an amount in box 7 required you to file as self employed (Schedule C or C-EZ) and pay self employment (FICA) tax in addition to income tax.
