Attack Puffin (real)

The auction bot is telling me I don't have the items I bid, which isn't true. I triple checked I have everything I offered, and yep. I've already been auctioned banned before because of steam trade issues. Will this be the final straw?

I have 0 items in my site inventory but when I try to deposit more than 2 items for my secret santa, it says I've reached maximum storage.

This year my gift recipient is a Heavy main. That would be a nice but not over-the-top gift? Like a strange weapon, or killstreak kit.

Self-explanatory title

In the tf2 items tab or in scrap.tf? Thank you for the help

It says I have no keys in inventory to trade, when I have a tradable Summer 2022 Cosmetic Key. How do I resolve this error?
