Yes and yes. You will want to wait until you get the 1099-B to know what has been sent to the IRS. If your 1099-B shows up with inaccurate information, you will want to have it corrected. The IRS has not opened for e-filing 2021 returns. Your return will be queued for e-file if you submit before the IRS opens.
Yes, you can upload a csv file but it will need to be mailed to the IRS with form 8453 and 8949 after e-filing. Wait until return is accepted and then mail if you are filing so far ahead of IRS opening.
It is always better to make sure the forms you get are correct before filing your return. It is also best to wait until the IRS actually opens.
