Education Tax Break

So, I am a full time student. I am independent on filing my taxes and have been for a few years. For the education expenses, I want to write off my computer as it was required by my IT classes. The problem is, I no longer have the receipt. I can find where I purchased it in my bank statements but it’s very vague and only says “Walmart” 🥲 how could they know I used it to purchase my computer with? I’m very worried about getting audited for it. It was a pricey desktop as I needed all kinds of software on it and programs to be able to code with. Any tax prepares in here?
