IEEE disclosing resubmission at peerj
Usually, such kind of notes refer to manuscripts rejected by the same journal, not by other journals. In this case, the IEEE transactions on signal processing. The manuscript ID of the previous submission allows the editor to recover information about the previous process.

The IEEE Signal Processing Society policy 6.16, though not explicit, hints at the above interpretation (bold mine):


  If authors indicate instead that their manuscript is a resubmission, then they are required to upload a supporting document detailing how the new submission has addressed the concerns raised during the previous review. Authors may also request that the resubmission be handled by the same Associate Editor, if the Associate Editor has not retired from the board. The Editor-in-Chief will do his/her best effort to accommodate the author’s request while taking into consideration the balancing of the workload among the Associate Editors of the editorial board of the journal. A new Associate Editor may also be assigned to the manuscript by the Editor-in-Chief.


Indeed, the highlighted possible request is feasible only if the resubmission is to the same journal.

Thus, you should simply make a new submission, without reference to prior submissions to different venues.

When, instead, you are submitting a revised version of a previously rejected manuscript to the same journal, you can report the previous manuscript ID in the cover letter.
