Deductions & credits

Got you. Do I need to provide any evidence to IRS that I paid the 3100$ bonus back to my company?

In addition, is there anyway that I can do it with online version? I find the desktop version turbox is really difficult to use...

 

Another question, can I submit my tax return online if I have to use desktop/download version? I don't want to print out my tax return forms and mail it...
