Two W2s from same employer BOTH with same Fed Employer ID in box B

Hi,  I reading reading some posts that suggest TT online wont accept the filing of two W2s that have the same Fed Employer ID - is that correct?

 

To explain, I know I will be getting two W2s from my employer at the end of this year relating to a change in payroll processing that will be reflected in a change in the "control number" (box d) of one of the W2s vs the other.    I understand one W2 will reflect earnings up to the change and one will reflect earnings after the change - but again my employer will not of changed.    I am reading some posts that suggest I should combine the values of the two W2s and file as one W2 in TT online, but that makes me uneasy given I assume the IRS will be receiving both W2s. 

 

Thanks Richard
