Quote from @Rud Sev: Hi Michael,Thank you, I will message my CPA asking for a more detailed explanation.I've been inquisitive with my CPA, but unless I ask question I do not get explanation (and unfortunately not a walk-through), although I've shown interest understanding this further and further.I'll try to reformulate my question more clearer (and with more data) - the problem that I have and will have is figuring out if my questions and confusion are due to a lack of understanding on my part, or my CPA is truly making mistakes.Regarding carry back, thank you for this info.
