only the IRS knows if you need to take action, Turbotax gets no info once accepted. the take action alert may have been due to theIRS receiving your original return which was missing the w-2. since you already submitted an amended return you may need to do nothing further. even e-filed amended returns take a long to fully process because I believe that it needs manual review to be finalized. the total time from submission to fully processed can take 6 months or more. be patient.
can't say why the REP said that your info couldn't be pulled up. it could have been because their computer system was overloaded at the time. The IRS computer system is outdated and attempts to modernize have failed. you're lucky that you even got through on the phone because the IRS is getting more calls than the system and agents can handle.
