Hello, I transferred my 401 K from Fidelity to Van guard- old employer to new employer's 401K company. I received a W2 from Fidelity with the amount and they say there is no tax liability and all other parameters on the W2 were zero dollars -. I f I add the amount on the W2 on turbo tax under income it takes off a tax amount? So I do not put this under income?
