Once a tax return has been Accepted by the IRS or a State, TurboTax receives no further information concerning the tax return or the status of any tax refund. Only the taxpayer listed on the tax return can obtain the status of a tax refund or a tax return.
If the check was lost then you need to have the IRS start a trace. Go to this IRS website for information - https://www.irs.gov/faqs/irs-procedures/refund-inquiries/refund-inquiries-0
