A few brokerages don't report to the IRS. Instead of entering every transaction on a form 8949, am I required to print a copy of all transactions and email to the IRS?

If you have some sort of account that has no reporting to the IRS - or you are summarizing transactions where the basis was not reported, you have to either enter every transaction on the 8949 or send a printed statement along with Form 8453 by mail (not email) to the IRS. You can still e-file your return, but you would need to send the details to the IRS by regular US mail.

Thank you, do I still add the cost basis up myself and put it in there or just leave it blank and the IRS will calculate it when I send the information in? just wondering whether or not to go ahead and put it on the form since I know what the cost basis is, I just don’t have proof of it. Thank so much for the great answer!

Yes, you need to enter your basis for transactions that are missing it. Otherwise, your taxable income will likely be overstated, and you will owe more in taxes. The IRS does not have a record of your basis, and even if it did would not make corrections.
