Don't worry about it. Besides, the landscape format reports are only for your records as well as used to track history and a few other things. Neither of the two landscape format ones are sent with any tax return. If one is required to be sent, it's the main one that prints in portrait format. To see what it looks like, see https://www.irs.gov/pub/irs-pdf/f4562.pdf
Generally, it only gets included with a filing if something changes - such as adding or selling an asset or something like that. In the end, if the IRS needs it, they will send you a letter specifically and explicitly requesting you send it. The important thing here is that you *do nothing* until and only if the IRS sends you a letter. It's not a big deal really.
Just understand that if you do get a letter from the IRS, follow the instructions in that letter to *absolute* *perfection* and do not deviate from those instructions one single iota. Otherwise, it just makes things worse.
In most cases, the last human to physically read a mailed tax return is the person who put it in the envelope. The IRS robo-bots remove them from the envelope and run them through a scanner to get them into the system electronically. Then any issues found by the IRS computers results in a computer generated letter, of which the first human to touch it and read it is the recipient of that letter.
So if you ever get a letter from the IRS for any reason, that's why it's important to follow the directions in that letter "exactly". Letters from the IRS all have a form number that will be in the upper right or upper left of that letter. That form number starts with the letters "CP" or "LTR" generally followed by 2-5 digits.
