Normally, I would not have this situation so do not want to do the estimated tax at the $400+quarterly that the system printed when I did my taxes. The gambling winning was what took me over the $1000 limit to have a penalty applied not work income. Is there a way for me to submit money directly to IRS if a gambling win happens in future?
You can throw away the 1040-ES forms if you want. There is no requirement to file them. It's just that if you underpay your taxes during the year, the IRS has a field day as they assess penalties and fines for that.
To avoid that in the future, the next time you receive a substantial amount of income on which taxes are not withheld, you'll want to send the IRS at least 25% of that income ASAP. YOu can do that at any time you wish on line at http://www.irs.gov/directpay
