This is especially frustrating because the amounts generated by Betterment/Wealthfront's tax loss harvesting features are fairly minuscule and, obviously, if those robo advisors didn't provide the numbers, a retail investor isn't going to be able to furnish them. This is just sloppy programming with logical fallacies. Loading this embedded sheet is the slowest part of the filing experience, and it re-loads for every missing date. So, 30 times I had to enter a blank. There was no validation informing me that blanks were not accepted (despite the process moving forward). So then at the end of the filing process I had to enter stub dates 30 more times, with no indication of whether it was working or not, and some dates required me to approve 2 or even 3 times.
The software behind this feature barely works--it doesn't even tell you what row you're filling in on each pass! Then, when scrolling through the embedded form, there is lag and a huge portion of the information is cut off. It appears this hasn't been investigated by an engineer since first being reported, I strongly recommend it should be.
