Default [Q] Can't push files with ADB/TWRP

Here's my issue. Trying to put an updated CM on my kindle. Put when I open up cmd prompt from my ADB file location from my desktop it won't let me push files.
I'm able to put in the cmd; adb devices. and can see my device is listed in recovery mod. but every time I run the cmd, adb push /sdcard/ doesn't send instead the cmd prompt returns a bunch of lines of code explaining the different commands that are available.

I've reinstalled the USB drivers for my kindle and am running TWRP v2.6.3.1.

Any help is appreciated

Edit: solved my own issue, sorry
