You cannot use your pay stubs to report income that is reported on a W-2. The IRS receives a copy of the W-2 from your employer and the pay stub in almost all cases will not match the W-2. You should wait for the W-2 since as stated the employer has until January 31. 2024 to provide the 2023 W-2.
If you did file now with the information you have your e-filed return may be rejected by the IRS. If not and it was accepted then in a few months the IRS will be sending you a letter questioning the status of your W-2 income. Then you would have to file an amended return using the wage data from the W-2 you received in January. It can take the IRS 20 weeks or longer to process an amended tax return.
