So, I reviewed my tax forms and just found out that instead of putting my 1099 in, I accidentally put them down on as w2. Should I amend?

Did you e-file the return?   If you e-filed and the incorrect tax return has been fully processed, then you should amend it to make a correction.    If the return has not been filed, then do not click on anything that says "amend."  You only use the "amend" process for a return that has been fully processed by the IRS.   If you have prepared----but not filed -- your tax return, then you need to delete the incorrect W-2 entry and enter the 1099 in the correct place in the software.   What kind of 1099 do you have?   There are over a dozen kinds, so where you enter it matters.
