Thanks for your help. I read line 17 and it actually said: if 0 or negative, you have no foreign tax credit for this category of income. I don't understand why, but it is a fact. I am just trying to understand if I can ever carryback.
I checked taxes I paid from 2012->2019 where line 17 was positive and I had potential carryback income from the following year and found 2 years where I could carryback.
In 2015, I had potential carryback income from 2016 of $2920 and paid $284 taxes.
In 2016, I had potential carryback income from 2017 of $2662 and paid $176 taxes.
In 2017 itself line 17 was minus -does this make a difference?
Of the possible $285 and $176 = $481 refund, I have general category and passive foreign taxes so it would only be about $285*.51 and 176*.31= $200. It is probably not worth the effort.
Can I carryback from 2016-->2015 and 2017->2016. Is this within the allowed 10 years?
