It is an IRS regulation not to allow more than 35 characters, we would never impose this ourselves as it is honestly ridiculous.
You can see the restrictions here: https://www.irs.gov/pub/irs-pdf/p4164.pdf
(Page 18)
As the IRS will not allow us to electronically file any return with more than 35 characters in the address line, we ask you to format your address to comply.
Many companies will allow you to have a longer address. However, this means you need to either Paper Mail your return, or they actually CUT off your address mid-way. We would never do this as this could lead to misplaced mail between you and the IRS and potentially lost notices or refunds.
So please don’t get frustrated at us; we are as transparent as possible to make sure your return is filed as accurately as possible!
