I owed/paid a balance with my 2016 Federal and California returns. After discovering a mistake I filed an **amendment** to 2016 Federal and California returns and received a refund from both. The California refund arrived in August, 2017. I did not receive a 1099-G in 2018 for the California refund and when I contacted the California FTB they confirmed their record of the refund and explained that the 1099-G would not be sent until 2019. I am trying to decide if I should go ahead and enter the refund in my 2017 Federal return w/o the 1099-G or simply wait to enter it in my 2018 return. I am inclined to do the later as that seems to line up best with when the IRS will receive the information from California.
Any advice one way or the other?
