Can you go back and change status to married filing together not separately.

Yes

Do you need to amend a filed return or change a return you are preparing?  But yes you can amend MFS to Joint.  You just can't amend from Joint to separate.

Yes, but it's a bit complicated.  If you filed 2 returns as "married filing separately" and want to change to "married filing jointly", then you pick one of the returns, start to prepare an amended return, and add the details from the other spouse.  When you file the amended joint return, both separate returns will automatically be canceled, you don't do anything special to cancel the other separate return.

However, there are some details about "adding the other spouse's information" that are more complicated than doing it automatically, to make sure the income tax and refund are correctly calculated.  Some instructions are here.
