What the IRS has said, is that if you claimed EIC, and the UEC changed your EIC eligibility, they would also adjust the EIC.
If you think you can get more EIC, you can try and file an amended tax return, but the background for the amended return must be the tax return after the IRS UEC adjustment and not the return you originally filed. Getting Turbotax updated to the current return on file with IRS can be tricky, and you will probably need your IRS transcript so you can understand all the adjustments and make sure your tax file matches the IRS before you start amending.
