You still have not explained what type of account you are selling. If just a regular brokerage account - not an IRA, then as I said before, you can use that money to fund an IRA contribution as long is the contribution is not more than yiu earned income. For self-employed that is the 1010 Schedule 1, line 3 amount minus line 14 (your self-employed income minus the deductible part of the SE tax).
If you are taking the money FROM an existing IRA then putting that back into the IRA as a contribution then that makes no sense at all - it would not gain anything and you would have to pay tax on the distribution.
