So I texted back 'Thank you for doing that. I still need to get the exact car registration numbers for you. Do you want to review together before filing? Last year taxable income was 5k lower. Just not as much interest on house I guess?' I don't know how he'll read it, but it feels like 'what the hell did you screw up this time' and I really don't mean it that way! Is there any other way I could have handled this?
I don't think it reads in a negative way at all, I think you handled it just fine.
