Can I withdraw request to extend

[VolvoGirl]

I don't think you can.  Why?  It shouldn't make any difference or affect your actual tax return.  Were you making a paymente with the extension you don't want to pay now?

you can't nothing prevents you from filing now.

Even if you requested an extension, you can go ahead and file when you are ready, even before April 15 if you want to.    Why are you wanting to cancel the extension request?   With or without an extension, your tax due is due by April 15.
