The fact that TurboTax uses AWS is apparent in the URL. Also most of the internet uses AWS anyways--I also work with tech and use AWS often. When I send a process to AWS and it hits something like memory error the process will just die. Given TurboTax is failing to generate the tax forms when there's a high number of transactions, I'm fairly certain the TurboTax software is hitting a memory limit. (This is more or less confirmed by the IT person I was speaking with who said the web-app cannot handle more than 500 transactions).
I'm going to try to confirm this theory by watching the memory usage when I try to generate my tax forms on the locally installed application, since this shouldn't be using AWS at all and use my local compute resources. If all goes well with using the locally installed app, then I'm right and TurboTax needs to give us "power" users the ability to download the software to generate our tax forms locally. If I'm wrong about the memory issue then the TurboTax software itself may just be messing up the imports somewhere and I need to double check every single line manually. In either case, I'll report back what I find. But I REALLY should not have to be jumping through this many hoops myself (as a paying customer) to figure out problems with their software.
