Yes, anything your brain can do there is a Turing Machine that can do them too, including committing all your errors;  but there are lots of Turing Machines that can do lots of things that your brain cannot.  However your brain does have one advantage, it's a real physical thing, but a Turing Machine is not, it's more like a schematic diagram of the underlying logic of a brain or computer at the most detailed and fundamental level possible. A Turing Machine can't calculate anything unless it's actually constructed, and for that you need atoms.

Yes, you can be considered to be a Turing Machine, a particular Turing Machine, but you are NOT ALL Turing Machines

All Turing machines have the same computational capability.

/"A Turing machine is a mathematical model of computation describing an abstract machine that manipulates symbols on a strip of tape according to a table of rules. Despite the model's simplicity, it is capable of implementing any computer algorithm."/
