pls need help in a couple hours!!!!

I am coming to you for some important tax advice, and t am hoping you can help me. theard that you were very prompt at replying to your clients! t am a commission salesperson for Zen Boutique the. During the current yeas, in add tion to my salary of $92,500,1 received $14,700 in commissions selling Zen masks. These things practically sell themselves! The reason why I am reaching out for advice is that my sister seems to think I can deduct the costs that I have incurred as employment expenses. She's protty clever, having taking accounting in the first year of her HR program. My advertising costs were $12,000, and ispent $0,400 on client entertainment. Because of the extensive travel required by my employer, my travel costs totaled $16,100. My employer also paid for my spouse to join me in iceland when I was there on business. Thankfully too, because t couldn't really afford to poy the ertra $800 for his flight. I am hoping to deduct as much as I can because f am required to pay all of my own expenses and I do not receive any allowance from my employer. Also, my sister said I am supposed to have something signed by my employer? Do you know what she might be reterring to? Any help you can provide would be greatly appreciated. I don't really know much about taxes. I look forward to your response
