Retirement tax questions

These are all useful information. Thank you @macuser_22 @Opus 17 

 

1. On Form 5329, should I use my current address or address at the time of filing?

2. Form 5329 instruction ask to include a check when mailing in the form. I don't have checks. I can pay online at IRS.gov. Should I pay online and include a copy of payment confirmation in each year?

3. How can I separate each year's Form 5329 when I mail them so IRS process all the years and don't get confused with all the paper?

 

Thanks again!!
