If you did a DITY/Partly DITY move you should have two W-2, your regular one and the Travel/Miscellaneous one (see picture). If you had more expenses than reimbursements, then those are your allowable expenses to deduct and you can enter them in TurboTax. If you do not have more expenses than reimbursements then skip the section.
Please see Publication 521, Moving Expenses for detail information what can be deducted.
And for the reimbursement of the partial DITY move if its included on a W-2 then the W-2 needs to have the code P on it as long as you did submit all the paperwork after the move.
