Got 1099G for 2015 ammended state return refund. Tryin to enter as additional 1099G and program is asking for total payments and withholding but not clear for which year?

I'm entering a 1099G for 2015 as an additional 1099G and on the "Tell us about your refund" page it asks for the total payments and withholding.  Its not clear if this is for 2017 or the year of the amended return?
