Yes you were supposed to wait for your W-2's so that they could also be entered on your 2020 tax return. You can only file ONE tax return. The IRS is not accepting or rejecting 2020 returns until February 12, so your e-file is just sitting on a server in pending now, and you cannot change it. Wait to see if it is rejected or accepted. If it is rejected then you can add the W-2's and re-file. If they accept it, then you have to wait and file an amended return later to submit the W-2's.
