I had this issue in this tax season. I filed only 3 returns but when I filed the 3rd one, It didn't go through because I reached the limit of 5. I called turbotax and the specialist said it would be ridiculous if the software counts the rejected returns as 1 attempt ( One of the return I had to file twice because it got rejected due to his long and complicated name), so she advised me to I efiled again and still failed. Then, when I called for another specialist, she said rejection is counted as an attempt. so I filed 3 times + 2 rejections=5 limits.
I think it's ridiculous to count the rejection as an attempt. I paid for 5 returns, then it should be 5 different returns, not by how many time I transmit 1 return.
