What number? Do you mean your AGI? Dd you transfer 2019 in to 2020 when you started the 2020 return? if so it should already be there. If you did not use the exact same account and user ID you will have to look it up.
You have to access your own account and/or print it for yourself using exactly the same account and user ID that you used when you prepared the return.
