TLDR: submit as a summary then upload your 1099-B as a PDF when prompted to attach.
"The error messaging you are seeing with regard to the wash sale entries is a result of automatic rounding of the number imported from your broker or typed in by you. If the wash sale adjustment is $0.49 or less, then it is automatically rounded to zero. This type of rounding is allowed by the IRS. Unfortunately, zero is not a valid value for this field -- thus the error message."
I decided to go back into my 1099 form that I uploaded and start editing the 144 transactions that need to be left blank leading to this being fixed. Some .22cents and some .48cents but all random amounts below .49cents. This required me to go back into the form and edit it. Going through this website can be a real slow pain when it comes to navigation. Having to page through close to 700 sales only 1 page at a time was very frustrating. With some research I did find that I could input the numbers from the 1099 as a summary (pretty easy to do) and then mail all 100+ pages to IRS with along with a 8453 IRS Form. I ended up going that route because with the loading pages it took about 5 minutes per correction to do. However to my surprise, after entering in the numbers for the summary I was able to upload the 1099 as an attached PDF.
