Is there a way to make this disabled 2FA wallet to a standard wallet besides sending bitcoins to a standard wallet?
You have to create a new wallet which would be a standard (single signature) wallet and send your coins there.
And also coming back to the comment of Sunderland on my first post, he mentioned that "The fees are not affected by the amount of BTC you send, but it depends on the outputs of that transaction.
e.g: Sending 3 outputs of $20 will be more expensive in fees than sending 1 output of $20."
So since there is no extra fee covering that 1 output, there are now only 2 outputs. What is the basis of the outputs? How can it be to be 1 output only?
The more the inputs and outputs, the more the fee. The second output will likely be the change address. The difference in the fee will be minimal.
