The IRS began to accept 2020 returns on February 12. If you are seeing an increased refund on the IRS site, the IRS has made that change. TurboTax gets no information at all after you file your tax return. If your daughter paid tax on unemployment then a good guess is that they have recalculated her refund for the tax law change regarding taxing unemployment. You will just have to wait for the IRS to finish processing the return and send the refund.
