How's best to go about this?

Yes. Unfortunately, I wasn't aware I'd overstayed until I was at the airport being questioned. It was a matter of less than two days. I'd clumsily miscalculated my 90 days as 3 months, so in my head I was leaving the US a day early, not two days late. Stupid, silly mistake, and now I'm paying for it.

May I ask what the reasoning is behind not applying until the summer or later? I'm just wondering what those couple of months difference will make to the possible outcome.

Thank you.

Just my completely unprofessional opinion, and just a general rule some people on this forum advise...best to stay in your home country for about 6 months before attempting to travel again. I based it off your attempt to re-enter the US in December 2017.

I see no reason for you to wait until summer. Just apply for the eTA now.
